Critical Warning: Failed on All Core Function

By jaurioldm17 on August 13, 2025

I am writing this review to save other developers and site owners the immense amount of time I have just lost. I needed to implement standard GA4 e-commerce tracking on a professional WordPress/WooCommerce site. Based on its popularity and countless recommendations, I chose GTM4WP as the solution to generate the required dataLayer.

Unfortunately, after days of intensive, professional-level debugging, I discovered that the plugin was completely non-functional in my specific—yet very common—environment.

The plugin failed at its two most essential tasks:

  1. GTM Snippet Injection: The plugin's most basic feature—injecting the GTM container script into the website's <head> and <body>—did not work at all. The script was simply not present. I had to bypass this functionality entirely and inject the code manually using another method (Code Snippets) just to get our GTM container to load.
  2. E-commerce dataLayer Generation (The Deal-Breaker): This is the primary reason anyone uses this plugin. After successfully loading our GTM container manually, I ran a full test purchase. By analyzing the GTM debug mode and the site's dataLayer object, I can confirm that GTM4WP completely failed to generate the purchase event and its corresponding ecommerce object on the WooCommerce order confirmation page. It produced absolutely nothing.

My Technical Environment (Please read this before you install):
To help others, here is the stack where the plugin failed. This is likely the source of the conflict:

  • CMS: WordPress
  • E-commerce: WooCommerce
  • Theme: Hello Elementor (using a child theme)
  • Page Builder: Elementor Pro
  • Key Detail: I am using Elementor Pro to customize the WooCommerce page templates, including the "Thank You" / "Order Received" page.

Conclusion:

My conclusion is that GTM4WP is fundamentally incompatible with themes or page builders that override default WooCommerce templates—a standard practice for virtually any custom-designed website today. Because it cannot handle this common scenario, the plugin proved to be entirely useless for my project.

While it may work on simple sites with basic, unmodified themes, it is not a reliable solution for professional, customized builds. The time and effort wasted diagnosing this incompatibility were substantial. I cannot recommend this plugin and strongly advise users with a similar tech stack to seek a manual implementation from the start.

Thought this was beginner friendly. Is not.

Poor Support Experience

By Shubham Verma (s4shubhamverma) on December 2, 2024

I’m disappointed with the support for this plugin. I submitted a question over a week ago, but I have yet to receive any response from the support team.

While the plugin itself may work fine, having reliable support is critical, especially when issues arise. Unfortunately, the lack of responsiveness has made it difficult to trust this plugin for long-term use.

I hope the team improves their support response time in the future.

I was trying to make GTM work with Litespeed cache plugin for hours

By quentintaran on October 20, 2024

I was stuck for hours trying to tweak the litespeed cache plugin so it'd work with Google Tag Manager. The solution was simple: use gtm4wp.

For some reason, this plugin avoids the conflicts with litespeed cache (allowing your tags to fire). I'm so happy this works because my site really needs the performance boost from litespeed while being able to track results.

A huge thank you to the developper!

Works well. Needs UI improvements

Good plugin to integrate GTM. The UI can use some polishing up.

no support and breaks page

By mcdeth on July 29, 2024

Support is nonexistent, enabling tracking post pages will break your site if it's not a post not woocommerce page. Excluding administrator from tracking doesn't work neither.

Literally a nightmare with no responses from plugin author

By kirstylmarks on March 27, 2024

Plugin Author,... Maybe start responding to the plethora of questions regarding issues with your plugin in terms of the latest updates and i may just improve my rating. Otherwise this has been a nightmare across all our key conversions

GTM4WP to the rescue

By jussipv on March 26, 2024

Since the "official" Google Analytics plugin for WooCommerce was broken by the developers and has been for weeks now I had to start looking for alternatives.

I've used GTM4WP before as well and to be honest I'm not sure why I ever switched.

Switching back to GTM4WP I can finally get conversions recorded again in my GA4! This is amazing! Why is this plugin even free? Would easily pay for it
